Yeah you can access Darts if you have enabled IE MODE on Edge.
Here's the link to darts :
https://www.flyordie.com/darts/
if you want to play Darts again and have the Microsoft Edge Browser then follow the steps below.
1. Open The Microsoft Edge Browser.
2. Click on Options in the top right of the Browser (3 Small Dots).
3. Click on the Settings option.
4. Search for IE Mode in the Search Box.
5. Scroll down until you see ''Allow sites to be reloaded in internet explorer mode'' (IE Mode).
6. Set the option to ''Allow''.
7. Load up www.Flyordie.com/darts
8. Login to the game.
9. Install the FlyOrDie Java Plugin when it prompts you asking you to (it might say it won't work after you install it but ignore that message if it pops up, I had that and it worked for me anyway).
10. Reload the website after you've installed it and done the above.
You should now be able to connect to Darts on your Edge Browser.
Kind Regards, Jeff.
